Embodiment 1

[0053] figure 1 It is a schematic diagram of a train dynamic adjustment method under an emergency in Embodiment 1 of the present invention. Referring to FIG. 1, the method includes:

[0054] S1 records the historical mapping data under all emergencies, collects the data information of the train in the same direction during the same period of the current emergency, determines the operating scene conditions of the train, and builds a scene library according to the data information and operating scene conditions;

[0055] S2 retrieves the historical mapping data corresponding to the same period of time and the same direction under the current emergency, and establishes an environmental model based on the historical data set according to the historical mapping data and the Markov decision process;

[0056] S3 establishes an environment model according to the scene library and the environment model based on the historical data set, and learns the environment model through an agent ...

Embodiment 2

[0139] Figure 6 It is a schematic diagram of a train dynamic adjustment system under an emergency in Embodiment 2 of the present invention. Referring to FIG. 6, the system includes: an information collection module, a data storage module, a scene library building module, a model training module and a model output module;

[0140] The information collection module is used to collect the data information of the train in the same direction in the same period during the current emergency;

[0141] The data storage module is used to store the data information collected by the information collection module and store the historical mapping data under all emergencies, as well as the operating scene conditions of the train;

[0142] Scene storehouse builds module, is used for calling the information in described data storage module, carries out scene storehouse builds;

[0143] The model training module is used to call the historical map data in the data storage module and the scene ...

Embodiment 3

[0156] Figure 7 It is a schematic diagram of the simulation interface of the train dynamic adjustment system under the emergency of the embodiment of the present invention 3, referring to Figure 7 , the system includes 5 parts: information collection module, data storage module, scene library building module, model training module and model output module.

[0157] Wherein, the content in the information collection module includes train number, train status, train running direction, emergency type and train schedule information. This module can collect the information of any train in the basic plan operation diagram of the train. Taking the train G17 of a certain train on the Beijing-Shanghai High-speed Line as an example, the train status is set to be in operation, and the train running direction is automatically set to down according to the train number. , the emergency type is set to natural factors: strong wind (level 8), and the train timetable information automatically...

Abstract

The invention provides a train dynamic adjustment method and system under emergency events, and the method comprises the steps: recording the historical map adjustment data under all emergency events,collecting the data information of trains in the same direction of the same time segment of the current emergency event, determining the operation scene conditions of the trains, and building a scenelibrary according to the data information and the operation scene conditions; establishing an environmental model based on the historical data set according to the historical map data and the Markovdecision process; according to the scene library and the environment model based on the historical data set, deep reinforcement learning is carried out through an agent, and a train dynamic adjustmentmodel is obtained; and carrying out on-line dynamic adjustment on the actual performance running chart of the train in the same direction of the same time segment of the current emergency through thetrain dynamic adjustment model. According to the method, the solving speed and quality of dynamically adjusting the approximate optimal feasible solution are improved, and the dynamic adjustment problem of the train actual performance running chart in an emergency is solved.

Description

technical field [0001] The invention relates to the field of railway operation scheduling, in particular to a method and system for dynamically adjusting trains under emergencies. Background technique [0002] With the proposal of the strategy of “Traffic Power, Railway First” and the construction of a huge operating mileage, the modern high-speed railway network of “eight horizontal and eight vertical” will realize interconnection in 2035. The running state of trains under networked operating conditions has the characteristics of nonlinearity, rapid evolution, and instability. If a fault occurs on the line is not handled properly, the delay of a train on the line will quickly spread to other trains on the line and to other trains on the line. Cross-line trains adjacent to the line will directly affect the operating capacity of the railway line and the operating efficiency of the train. At present, the emergency response to railway emergencies is still mainly handled by the...
